What if there are multiple nested aggregations with a scan locations
in a dataset? Where does the "recheckEvery" go, in the outer most
aggregation, or in the inner most aggregation?

<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";>
<aggregation type="union">
<netcdf>
<aggregation dimName="MT" type="joinExisting" recheckEvery="6 hour">
<scan location="/hycom/ftp/datasets/GLBa0.08/expt_90.9/data/"
suffix=".????_???_00_2d.nc" subdirs="true" />
</aggregation>
</netcdf>
<netcdf>
<aggregation dimName="MT" type="joinExisting" recheckEvery="6 hour">
<scan location="/hycom/ftp/datasets/GLBa0.08/expt_90.9/data/"
suffix=".????_???_00_3zs.nc" subdirs="true" />
</aggregation>
</netcdf>
</aggregation>
</netcdf>

I ask this question because it looks as though some of our catalogs
are triggering hourly rechecks, even though the "recheckEvery" value
is not present in the dataset...

Any ideas?
